IGNITION APYARATUS FOR EXPLOSION-EIVGINES.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed May 1, 1914. Serial No. 835,662.

To all whom it may concern:

Be it known that I, EDWARD L. PARRIS, Jr., a citizen of the United States of America, residing in the borough of -Manhattan, in the city, county, and Stateof New York, have invented certain new and useful Improvements in Ignition Apparatus for Explosion-Engines, of which the following is a specification.

My invention relates to ignition apparatus for explosion engines, and the main object of my invention is to provide a simple and efficient means whereby with small battery power the necessary sparking maybe provided at the sparking-points when the magneto is not operating.

In these drawings I have shown my vibrating electromagnet as combined with an induction means in the form of a magneto having primary and secondary Windingson its armature.

In the accompanying drawings, Figure 1 is a diagram illustrative of my invention; Fig. 2 is a longitudinal section through the electromagnetic vibrator box; Fig. 3 is a transverse section through the same on the line 3-43, Fig. 2; Fig. 4 is a perspective view of the switching means; and Fig. 5 shows a modified form of vibrator.

The sparking points b, Fig. 1, may be connected in the usual manner on the one side through a conductor 9 to a ground F and on-the other side through a conductor 7 to'the high-tension secondary winding P of the armature of ;.the 'magneto G. The low tension primary winding P of this armature is 'connectedon one side through conductors 8 and 9 to the ground F and through the conductor 6 to the circuit breaker E, While on the'other side this pri mary winding P is connected through conductor 5, and the electromagnetic vibrator to the battery B, which is grounded at F. The circuit breaker E is also connected to the conductor 5, and across the conductors 5, 6 is connected the condenser D in parallel with the circuit breaker E of the magneto.

The electromagnetic vibrator, comprises an electromagnet C withingle low tension winding 1 connected at one end through conductor 1 with the battery and at the other end through the conductors 2, 3 with the spring contact plate 10 carrying near its free end, at the upper side, a platinum contact to make and break connection with an adjustable contact 11 in a fixed arm 12.

ppiece P, while to the other end of the core is attached an L-shaped piece 79 of iron. To

this piece 79 is pivoted at w the armature A to be acted on by the pole piece 79. This armature A has a connection with thefree end of the spring contact plate 10, as by a hook 13 on the armature engaging the outer end of the spring contact with an interposed piece of insulating material. The elasticity of this spring contact-plate is such as to constantly tend to come into contact with the contact stop 11, and to raise the armature A at the same time away from the pole p. The spring contact plate 10 and the fixed a rm 12 may be mounted onthe piece p with interposed insulation.

I may use any convenient form of switch to throw the vibrator into and out of action. In Figs. 1, 2, 3 and 4, I have shown the following switching means :Upon the piece 7), and over the arm 12, but insulated therefrom, I mount a spring plate 15., which as seen in Fig. 1- is split. One arm, 16, of this plate carries a pin 17 which tends to bear upon the armature A, while a projecting part of this arm, in the form of a washer 18, projects over the other and longer arm 19, Fig. 4, so that whenever this longer arm is raised, the arm 16 will be raised with it. The outer end of the arm 19 rests upon a cam 20 with two acting faces of different heights. By turning thls cam to a position with the arm resting upon the highest part of the cam. the arm will be held in the elevated position indicated in Fig. 1, with the armature A raised as shown by the spring contact plate 10. When the cam 20 is turned to bring its lower face under the arm 19,

the latter will by its elasticity (being' stronger than the contact plate 10) separate plate 10 from pin 11 and so cut out the vibrator. In this position the magneto circuit not being grounded allows the magneto to operate. If cam 20 be turned farther so that the arm 19 of the plate 15 comes in contact with bar 12, as seen in Fig. 2, the

magneto circuit will then be groundedspring plate 10 to rise into contact with con-.

tact 11, and at the same time raising the armature A. This closes the battery circuit through the winding of the electromagnet C, conductors 2, 3, plate 10, bar 12, conductors 4, 5, low tension primary winding of magneto armature G, and conductors 8, 9 to ground F The magnet C will instantly attract the armature A to break thecircuit again, and the vibrationswill continue so long as the plate 15 is kept in the raised position. The result is that they are inducedin the secondary windings P of the magneto armature'currents which will provide the required sparking at S.

It will be understood that the described operation of the battery can cause sparking at S only when the points E are open, and therefore when the piston of the engine is in position for ignition. On the other hand, since the battery furnishes an intermittent current, it will not injure the points E (the condenser D or primary windings P if the battery be put in operation when those points are closed. Accordingly I use only the usual single circuit breaker E. a

In Fig. 5 I have shown a modified construction of vibrator, inclosed in a box of insulating material. -In this case, the connections are slightly changed. The wire 1 from the battery isconnected through post B and conductor 101 to the stationary plate 121, which carries adjustable contact 111.

Against this may contact the vibrator 110, which is electrically connected to one end of the single low tension windings of the electromagnet G The opposite end-of thWinding is electrically connected to the binding post W, which is connected to wire 3. Opposite this post W stands the body of an elastic switch plate 150, which is mechanically and electrically connected to binding post M, connected through wire 4 to the magneto. The free end of thiselastic plate 150 normally tends. to assume the position shown in Fig. 5 and in contact with the backstop 140, which is connected to ground F through a binding post G. Against the back of the spring plate 150 may work a' cam or key 130, as shown. With the switch in the position illustrated, the magneto is grounded at F and' the battery cut out. If. a quarter turn be given to key 130, the ground connection at F will be broken, but the battery will still be out of circuit. By giving to the key 130 a half turn from the position shown, the spring plate 150 will bepressed into electrical contact with post W and the battery circuit closed through the coils of the electromagnet G causing the armature A and spring 110 to vibrate, as in Fig. l.
